Dependent claims

A container formed from foldable sheet material comprising an erected body member and a pair of erected liner members, said body member including:

a bottom panel having opposed sides and opposed ends;
a pair of end panels foldably joined to the opposed ends of said bottom panel and having a prescribed box height and defining hand openings therein;
and
a pair of side flaps foldably joined to opposite side edges of said bottom panel and having a flap height less than said prescribed box height;
and each of said liner members having a height substantially that of said prescribed box height and including:
at least one end section lying against one of said end panels of said body member and defining a hand opening therein;
at least one side section lying against one of said side flaps on said erected body member;
and
at least one foldable column section connected to said side section, vertically oriented and projecting interiorily of
said erected container;
said erected container defining an open top cavity therein with said end sections on said liner members overlying said end panels on said body member with said hand openings in registration and with said side flaps overlying a portion of said side sections in said liner members adjacent said bottom panel whereby said side sections and said column sections project beyond said side flaps;
and adhesive means bonding said end panels on said body member to said end sections on said liner members and said side flaps on said body member to said side sections on said liner members to maintain said column sections in an erected position.
each of said liner members including one of said end sections sized to correspond generally to one of said end panels on said body member;
including first and second of said side sections foldably connected to opposite ends of said end section and adapted to extend along opposite sides of said erected container;
including one of said foldable column sections foldably connected to the end of said first side section opposite said end section;
and includeing an edge flap foldably joined to that side of said one of said column sections opposite said first side section, said first and second side sections sized so that a portion of said second side section on one of said liner members overlaps both said erected column section and a portion of said first side section in the other of said liner members in the vicinty of said column section in the other of said liner members, said adhesive means bonding said edge flaps to the overlapped portions of said second side sections and bonding said second side sections to said first side sections in the vicinity of said one of said column section.
